Chicago-Latrobe 53128 Taper Shank Drill
This Chicago-Latrobe 53128 drill bit is a general-purpose cutting tool with a 7/16 in diameter and a 118 degree conventional point. It is made from high speed steel with a black oxide finish. The taper shank fits directly into compatible machine spindles or sleeves for secure drive.
Installation and fit
Insert the taper shank into a clean, matching Morse taper socket and seat it firmly so the bit cannot spin under load. A loose or worn socket is the usual cause of slippage and poor hole accuracy. The black oxide surface helps retain cutting fluid during the first cuts.
Sustained drilling behaviour
High speed steel construction maintains hardness at the temperatures reached in prolonged steel or iron drilling. The 118 degree point distributes cutting forces evenly across the lips, reducing edge breakdown during continuous feed. Black oxide coating resists galling when coolant flow is steady.

Questions about this item
How can I confirm the 118-degree point angle is cutting correctly after setup?
The bit should start drilling without wandering and produce even chips when used at proper speeds for the material.
What comes in the box and what must I buy separately?
The package contains the 7/16-inch taper shank drill bit only; a compatible taper-shank holder or Morse taper sleeve is sold separately.
Which version should I choose for general-purpose drilling?
The 53128 model with its 118-degree conventional point and black-oxide high-speed steel is the standard choice for general-purpose work.
